Paper Abstract

This paper presents a new pixel slide method using optical deices for digital still cameras with a single-CCD to achieve high resolution. Authors have developed a new pixel- slide method using a double-refraction plate, a liquid crystal plate and a polarization filter, which takes advantage of the fact that a double-refraction plate has different indexes of refraction depending on the polarization direction. In addition, they have developed a ne color interpolation method to create a highly precise image form two images shifted by 1/2 pixel. The interpolation is conducted utilizing the color correlation. When a VGA- compatible CCD was employed in a digital still camera, resolution of 800 lines was obtained by using the proposed method. When an SXGA-compatible CCD was used, resolution of 1600 lines was obtained.
